17Claims.

1 This invention relates to improvements in coin controlled and manuallyactuated dispensing devices and has-particular reference to such a device primarily adapted to progressively dispense commodities, such asfood prepared in removable containers.

It is an object of the invention to provide a device having a combinedclosure andsight door normally held closed by coin actuated releasemechanism and manually actuated to open position upon release of thecoin actuated mechanism to permit manual removal of the tray, dish or,

the like containing the article to be dispensed and upon removal of thearticle and a release of the door, permitting the door to automaticallymove to closure and latched position.

A further object of the invention resides in a. novel form of conveyingdevices for thearticlesto be dispensed, whereby they are; progressivelymovedto dispensing position automaticallyby gravity and whereby theconveying devices .are automatically moved from dispensing position andreturned to a point of loading when the access door is moved to closedposition, which action permits another conveying device toautomaticalsequent release.

Another object of the invention resides in auto-, matically actuablebaffle means to be positioned between a loaded conveying device indispensing position and a follow-up loaded conveyingdevice,

when the closure door is released andactuated to open position, thuspreventingaccessto the follow-up device at all times when the-door isopened.

Further important objects reside in novel control means for theconveying devices actuable-by the closure door in both the open andclosed position, the novel form of conveying devices and invention andwherein like characters of refer-. ence have been employed to designatelike parts throughout.

device is to be used asasingle vending machine.

The present embodiment of the invention has been designed primarily forthe dispensing of foods or the like and,since a plurality of the deviceswillbe employed, the rear wall-has been 1 dispensed with to permitaccess by an attendant.

cent the side walls 6. A closure door 9, having a sight opening l0,covered by a transparent sheet H, is movable in a vertical plane forcovering and uncovering the opening 8; The sheet I l provides meanswhereby 'an operator may view the food or other article that issupported in dispensing position.

Thedoor 9 issecurely held inclosedv position by a solenoid latch 12,engaging in a keeper 13,, carried by, the upperv edge of the door 9. Thesolenoid latch isrigidly supported on a horizontal nism,=to bedescribed, and to provide atable-like structure tofacilitate-theremoval.of thefood, etc.- The door .9 preferably travelsin channel,

Since it is contemplated that the :device is-to be employed in groups,arranged side by side or in superime. posed. relation, the top andbottom has been:

The frontwall l .isprovided with arectangular access opening 8,terminating adja- 3 guides l6, and normally rests upon the flange |5 inclosure position. A limit switch, not shown, is actuated when door 9 isclosed so as to throw solenoid l2 forward and thus lock door 9.

It is contemplated, that the article to be dispensed shall be conveyedfrom the rear or loading position, to a point of stop or dispensingposition by gravity and to accomplish this feeding;

means, upper and lower inclined tracks I! and I8 are secured to the sidewalls 6 and incline downwardly toward the front of the casing. Asclearly shown in Figures 6 and 7, the tracks are of unequal width, withthe lower track l8 being wider than the upper track Conveyor carriages9, of generally square or rectangular shape in top plan, are adapted totraverse the tracks IT and H3. The carriages l9 have an upper flatsurface for the reception of a dish, box or other receptacle, shown bydotted lines in Figure l.

Flanged wheels 23 and 2|, support the carriages I9 for traverse on thetracks I1 and I8 jointly, with the wheels 29 and 2| simultaneouslyengaging their respective tracks for maintaining the carriages |9 levelthroughout their travel upon the tracks to the point of dispensing stop.Said front wheels 29 are further apart than rear wheels 2|, as shown inFigure 3. Since the carriages are usually loaded at a remote point andthen placed upon the tracks, cams 22 and 23 are rigidly fixed adjacentthe loading end of the casing to facilitate the engagement of the wheelswith their respective tracks. As clearly shown in Figure 1, the trackterminates adjacent a trip mechanism, designated as a whole in Figure 1,by the numeral 24, as shown in detail in Figures 9, l0 and 11, while thetrack l8 terminates short of the track I! a distance sufficient topermit a simultaneous clearance of the wheels 2|] and 2| from theirtracks for a shifting of the carriage to a pair of return inclinedtracks 25 and 26. The tracks 25 and 26 correspond to the tracks I! andI8, but in this instance, the track 26 is above the track 25. The innerends of the tracks 25 and 26 are curved upwardly, as at 21 and 28,serving to direct the wheels 20 and 2| to their particular track. Theinclination of the tracks 25 and 26 is toward the rear of the casing soas to direct an unloaded carriage to a point for removal and reloading.

Each carriage is provided with a pair of forwardly directed hook devices29, spaced apart and having their hook ends 39 directed in axialalignment. The hook devices 29 coact with the trip mechanism 24 in amanner now to be described.

The trip mechanism 24 comprises a central plate 3|, having verticallyshiftable contact with the inner side of the front wall 1 and positionedcentrally of the device. A bracket 32 provides a guide for the plate 3|,with the bracket being rigidly fixed to the wall 1. The upper end of theplate 3| is provided with oppositely extending horizontal flanges 33,terminating adjacent the side walls -6, while the lower extremity of theplate 3| is provided with oppositely extending horizontal flanges 34co-extensive with the flanges 33. A retractile spring 35 has connectionat its lower end to the flanges 34, while its upper end is connected tothe bracket 32. The spring 35 normally tends to shift the plate 3|upwardly. The plate 3| is bent rearwardly to form a shelf-like section36, lying in the same plane as the flanges 33.

The plate 3| is then bent downwardly at a right angle, forming avertical wall 31. The terminal end of the plate is then rolled inwardlyand upwardly. as at 38, forming a spaced wall that terminates short ofthe plate 36. The opposite ends of the rolled portion are notched at310. on its forward face to a depth substantially half the rolledportion and having a length sufiicient to permit clearance of the hookeddevices 39, in a manner presently to be described. The wall 31 forms anabutment against which the hooked devices 3B normally rest as a limitmeans for the forward travel of the carriage to dispensing position, asshown by the solid line position of Figure 9. The wall 38 serves as astop to limit the initial tripping of the carriage on the opening ofdoor 9 to insure that the carriage will be held against shifting to thelower return tracks while the closure door 9 remains open, as shown bythe dotted line position of Figures 9 and 10.

The door 9 carries depending legs 39, parallel to the side walls 6. Thelower ends of the legs 39 are bent inwardly to form foot portions 49,adapted to contact the lower flanges 34, when the door is in the closedposition and to contact the flanges 33, when the door is moved to theopen position. The foot portions 40 shift the plate 3| and itsassociated parts either upward or downward at the extreme movement ofthe door in either direction by its contact with flanges 33 and 34 forthe purpose to be described.

Means are provided to shift a bafiie plate across the path of movementand between two adjacent and abutting carriages for preventing access tothe carriage next adjacent the carriage that is in dispensing position,comprising a vertically movable plate 4|, operable in guide channels 42,fixed to the side walls 6. The plate is moved in a vertical plane by apair of bars 43, located adjacent the side walls 5 on each side. Thebars slidably engage in suitable openings formed adjacent the lowercorners of the plate 4| and fulcrum intermediate their length between apair of rollers 44. The forward ends of the bars are pivotally connectedat 45 to the lower corners of the door frame 9. Therefore, movement ofthe door to open position, causes the bars to fulcrum over the rollers44 for moving the bafiie plate 4| downwardly. The bafile plate 4| ispositively moved in either direction by the movement of the door 9.

The solenoid latch device I2 is actuated by any conventional coincontrolled electrical switch, generally indicated at 45 and connected tothe solenoid by electrical conductors 41. A limit switch, not shown,serves to return the solenoid to locked position, as explained above.

In the operation of the device, an attendant loads the machine from therear by positioning a plurality of carriages upon the inclined tracks I!and I8, cams 22 and 23 acting as guides. Normally, the article to bedispensed is first placed on the carriage and the carriage then engagedwith the tracks. This loading is continued until the tracks I! and I8are fully loaded. The first carriage has been stopped in its forwardmovement by the abutment of the hooked devices 30 with the rear wall 31of the trip device 24, as best seen in the solid line position of Figure9. The following carriages abut one another, as seen in Figure 1.

The operator, customer, having viewed the article through thetransparent plate proceeds to insert a suitable coin in the coin device46 causing the solenoid latch to be tripped and the door 9 released, atwhich time the door may be manually elevated by the operator to itsuppermost position for removal of the article supported on the carriagel9. As the door 9 moves to open position; the bafiie plate -41movesdownwardly'toprevent access :to -.the\ next adjacent carriage. Thewall l4 likewise prevents aperson from reaching over the baflle plate 4i;

As soon-as door 9 'isunlocked, spring .35 acts to-lift plate 31 to apoint where it abuts the underside of flange l5. When thedoor has. beenmoved to its uppermost limit, the foot portions 48 have-engaged theflanges 33, lifting the plate.

3| to. a point Where it abuts. the underside of the flange It asa-safety in case spring 35 fails to work. At this-point,the notches3lahave been moved upwardlyva'distancevto permit "the hooks 30 passingtherethrough for: abutment with the wallet, as indicated in dotted linesin Figure.

9. Spring 351holds plate3l :up during the entire time'door 9 is beingmoved, until door 9 is closed and looked as explained below. This istheinitial trip. motion forthe carriage and, as shown, the carriage hasmoved forward a distance equal to the distance the hooksSilhavetravelled from the wall 3'! to the wall 38, which distance haspositioned the wheels 26 and 2| at the terminal endsof the tracks Handl8. After the article has been removed from .the carriage by theoperator, the door is released and falls by gravity to its lower orclosed position, raises the baflle plated! for providing clearance topermit shifting of the next adjacent carriage as the dispensingcarriagemoves forward.

At the fully closed and latched position of the door 9, the footportions 4!) bear against the flanges 34, pressing the plate 3!downwardly against the tension of the spring 35 and thus moving the trip24 to its original position. As the trip 24 moves downwardly, the wallsection 38clears the hooks. 3B, permitting the carriage to roll forward,its wheels and 2! simultaneously droppingoifofupper tracks IT and I8.and striking the curved ends 21 and 28 and dropping to the lower tracksand 26, at which time the carriage rolls by gravity to the loading orrear end of .the machine. Thus, the .entire shifting and control of thecarriages-isv under the influence of the closure door 9. The carriagewill beheld against release by 'wall 38 until'the door is fully closedand latched, when wall 38 clears hooks 30, thus preventing apartialclos-.-

ing of the door in order to release av carriage and permit anotherloaded one to moveiforward.

Carriages is are at all times level platforms and yet due to the angleof the tracks I! and I3 will roll down in themachine by gravity andreturns by gravity on tracks 25 and 26. At the same time the outerflanges of the wheels 20 and 2! are of the same diameter so that whenthe carriages are resting on a level table as in preparation for beingput into the machine, they willstill have a level platform.

It will be seen from the foregoing thata very novel and efficient formof vending machine has been provided. The parts are few and simple andeffectively-designed and positioned to accurately control the movementof the loaded and unloaded carriages therethrough. The-closure door andtrackwayspermit of gravity closing and feeding, with a minimum ofmechanical parts. The trip mechanismassures that a carriage positionedfor dispensing will be positively maintained in its position ofunloading until the door has been fully-moved to its lowermost position,at which time the latch is engaged and the carriage released to move toloading position before another loaded carriage can move into position.The-initial movement ofthe'car 1 in operation, is strong, durable, cheapto manu-- facture and highly eflici'ent and1 fool proof in.
